Miliaria rubra or prickly heat

Miliaria rubra, or prickly heat is caused by obstruction of sweat ducts in epidermal or dermal layers. This rash is common in infants and children, especially in the summer. It appears over the face, upper trunk, and intertriginous area of the neck, as a result of tight-fitting clothing. Wearing lightweight, loose-fitting clothing, eliminating greasy topical agents, and using corn starch or even talcum powder help get rid of the rash.
